“…Furthermore, common sorbents are low cost and made of various raw materials including (porous) inorganic materials (zeolites, activated carbons, clays), natural organic fibers (straw, wool, cotton) [1,2,3,4,5,6,7,8] and synthetic organic polymers (polypropylene, alkyl acrylate copolymers) [9,10,11]. However, these materials have some limitations such as low absorption capacity, poor recyclability, poor selectivity and are not environmental friendly.…”

“…The polymer-graed graphene foams prepared by Zhu et al exhibited outstanding C abs for chloroform at the beginning, but this capability soon decreased by ca. 33,35,37 However, bacterial cellulose aerogels have just been proven to maintain their C abs value for diesel for 10 cycles. 40 Pure carbon nanotube sponges could maintain their integrity and mechanical strength even with 1000 times of compression.…”

“…40 Pure carbon nanotube sponges could maintain their integrity and mechanical strength even with 1000 times of compression. 37 A cellulose nanobril aerogel lost 52% of C abs when only 6 absorption-compression cycles were done. Therefore, commercial foams might be better choices for porous substrates.…”

Ultrasoft gelatin aerogels for oil contaminant removal

We demonstrated the preparation of a novel aerogel simply by crosslinking a gelatin physical gel with formaldehyde (cGel) and using a subsequent freeze-drying procedure. A hydrophobic absorbent material (MTCS-cGel aerogel) was further obtained by thermal chemical vapor deposition (CVD) of methyltrichlorosilane (MTCS).Rheological tests were carried out to investigate the cross-linking between gelatin and formaldehyde. Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), energydispersive X-ray spectroscopy (EDX) and wettability of oil and water results proved that successful silanization occurred on/in the aerogels.These results also indicated that the MTCS-cGels had low densities (5-8 kg m À3 ), high porosities (>95%) with uniform pore sizes, and unique laminar/fibrous 3D networks. The oleophilic aerogels possessed high oil absorption capacities of 70-123 times that of their dry weights.Furthermore, the absorbents exhibited excellent elasticity and ultrasoftness with a stress of only 2.0 kPa at 60% strain. This property endowed the aerogels with super-recyclability where 83-85% of their full absorption capacity was maintained after 5000 times of compression. The high oil absorption performance, super-recyclability, sustainability, biodegradability and cost-efficiency make this novel absorbent a promising candidate for large-scale oceanic oil contaminant removal.

Porous hybrid hydrogels were fabricated by mixing cellulose (CEL) and soy protein isolate (SPI) solutions, followed by crosslinking with epichlorohydrin. Their miscibility, morphology, structure, and properties were investigated by wide‐angle X‐ray diffraction, thermogravimetric analysis, scanning electron microscopy, dynamic mechanical analysis, rheological measurement, and swelling tests. The results show that CEL performed as a “scaffold” of pore walls and contributed to the good mechanical properties, while SPI performed the role of an “extender” of pore size and was responsible for the high water absorbency. The incorporation of CEL (stiff chains) and SPI (hydrophilic groups) in the hybrid hydrogel constructed the porous structure. This work provides a method for the fabrication of hydrogels with porous structure through the combination of a stiff material as a “scaffold” and a hydrophilic material as an “extender.” © 2016 Wiley Periodicals, Inc.
